DUST-HOOD FOR HOT-AIR REGISTERS.

Specification of Letters Patent.

Application filed December 12, 1913.

Serial No; 806,169.

To all whom it may concern:

Be it known that I, CHARLES C. GERI-IART, a citizen of theUnited States, residing at Clar'ksville, in the county of Montgomery and State of Tennessee, have invented a new and useful Dust-Hood for Hot-Air Registers, of which the following is a specification.

My invention relates to .a dust hood for hot air registers applicable to registers or radiators located in the floor of a room, or, if my hood is provided with suitable supsuch moistening of the'hot air, the dust,

ashes, lint or other matter in the hot air to cling the closer to the inside of the top or cover and to the, airscreening means of the hood; third, to provide a dust hood for hot air registers that. prevents the hot. air from the heating source from coming into injurious contact with the walls or ceiling of the room, thus preventing the soiling smudging or scorching of the walls, wall paper, wood work or ceiling of the room;

and fourth, a dust hood for hot air registers which may be used in conjunction withoil or gas heaters for moistening the hot air emanating therefrom and concentrating the heat at the top thereof and distributing it in a desired direction in the room. I accomplish these objects by the device illustrated in the accompanying drawings in which Figure 1, is a side elevation of my dust hood for hot air registers. Fig. 2, is-a sectional plan View of my dust hood for hot. air registers on the. line 2-2 of Fig. 1.

Fig. 3, is an end elevation of my dust hood for hot air registers. Fig. 4:, is aview of my dust hood for hoti'air registers on the line 4. 1 of Fig. 1;

Similar numerals refer to similar parts throughout the several views;

My dust hood for hot air registers, which ismade of tin, galvanized iron or other suitable material, comprises a box frame, open Patented Oot.13, 1914.

at its bottom, having sides, 10, and ends,

11, a top or cover, 12, a hotair outlet, 13,

an air screening ledge or shelf, 14, and a water trough, 15.

The box frame is preferably rectangular in shape, the sides, 10, and ends, 11, of the box frame being attached at their lines of f meeting by soldering or in other suitable manner, the manner of attachmentshown in the drawings being the joining oflapping portions ofthe sides and ends formed by bending at an angle the edge of the sides or ends. The box frame is. open at its bottom to permit placing of the dust hood over the register or radiator, the open bottom being of sufficient size'to coverthe hot air area of the register-or radiator so asito receive all the hot air therefrom. The-box frame is provided with longitudinals, 16,

and crosspieces, 17, to strengthen it at its f bottom, the rear longitudinal, 16, and the cross pieces, 17, being formed by turning over at an angle the lower edge of the rear side, 10, and the lower edges of'rhe ends, 11, of the box frame, but I do not restrict myself to this form, as any suitable manner of providing longitudinals and cross pieces may be employed. v j

The front sideor face, 10, of my dust hood extends downward fromthe' point of junction with the top or cover, 12, for only a portion of the distance from the cover to the bottom of the box frame, leaving an open space between the lower line of the side, 10,

andthe front longitudinal, 16, which space serves as the hot air-outlet, 13, of my dust hood. j j v The top or cover, 12, preferably is convex or curved, upwardly, when viewed injcross section, toafford by reason of its. interior concavity a means of deflecting downwardly the hot air received through the open bottom of the box frame. The cover, 12, as shown in the drawings, is fixedly attached to the sides, 10, and ends, 11, but it may be hinged atvits rear and provided on its front with a latch or catch to secure the top orcover to the box frame and topermitopening ofthe cover, 12, themore readily to clean the interiorof my dust hood of ashes, dust or simiv lar matter. 1

'Theair screening ledge or'shelf,14=, is pro- .vided with wire gauze or other closely meshed material which will permit thepas sage of the hot air therethrough, but willretain ashes, dust, lint or similar substances. The air screening ledge or shelf, 14}, 1s supported in the box frame longitudinally or horizontally of the box frame on or slightly above the upper longitudinal line of the hot air outlet, 13, the ledge or shelf, 14:, extend ing inwardly in width into the interior of the box frame for only a portion of the width of the box frame, the intention being that the ledge or shelf, 1 should be located adjacent to the hot air outlet, 13, in such position as to receive and screen the deflected hot air in the hood before its passage through the hot air outlet, and yet not nterfere with Or screen the hot air as it s received directly from the register or radlator, as" such interference. or screening would cause the ashes, dust or similar matter to drop back into the register or radlator instead of finding lodgment on the ledge or shelf, 14. The ledge or shelf, 14, is inclined downwardly toward its inner edge the better to receive and screen the deflected hot air, its inner edge beingslightly raised or beaded to retain the ashes, dust and similar matter on the ledge or'shelf.

The water trough, 15, is arranged longitudinally of the box frame near the bottom thereof on the side opposite the a1r screening ledge or shelf, 14. The water trough, 15, is open at its top to allow the moisture therefrom to mingle with the hot air, and is provided at oneend with an extension, 18, projecting through one end, 11, of the box frame to permit the water trough to be supplied with water from the exterior of my dust hood. By placing the water trough, 15, near the bottom of the box frame, I afford greater steadiness to my dust hood inits position over the register or radiator.

In use my dust hood is placed over the register or radiator so that the hot air there- A from is received through the open bottom,

moistened by the water in the trough, 15, and deflected by the top or cover, 12, upon the ledge or shelf, 14, which screens it be fore its passage through the hot air outlet, 13, the dust, ashes or similar matter clinging .to the interior of the top or cover, 12, and

being retained also on the ledge or shelf, 14,

whence it subsequentlycan be removed from the dust hood.

For use with a side wall register or radiator, my dust hood may be raised sufliciently to cover the hot air area of the wall register or radiator by extending downwardly the front longitudinal, 16, as an addition to the side, 10, of the box frame,Ibelow the outlet, 13, and each end, 11, downwardly, thereby forming a stand or support for the dust hood, open at its back to receive the hot air from the wall register or radiator and which will also collect the hot air therefrom and transmit it to my dust hood through the open bottom thereof.

In using my dust hood on an oil or gas heater, it may be placed on the top thereof, it being constructed of sufficient size substantially to cover the top of such heater, the hot air being collected in the dust hood and moistened by the water in the trough thereof and distributed inthe room from the hot air outlet in direction in accordance with the position of my dust hood on the heater.

Having fully described my invention, I claim 1. A dust hood for hot air registers comprising a box frame open at its bottom to receive the hot air from the register and having a hot air outlet, a deflecting cover for the box frame, and a reticulated shelf in width less than the width of the box frame arranged therein adjacent to the hot air outlet whereby the hot air from the register is screened before passage thereof through the hot air outlet; substantially as set forth.
